Synopsis

Description

The fegetexceptflag() function attempts to store an implementation-defined representation of the states
of the floating-point status flags indicated by the excepts argument in the
object pointed to by the flagp argument.

The fesetexceptflag() function attempts to set the floating-point status flags indicated by
the excepts argument to the states stored in the object pointed to
by flagp. The value pointed to by flagp will have been set by
a previous call to fegetexceptflag() whose second argument represented at least those
floating-point exceptions represented by the excepts argument. This function does not raise
floating-point exceptions but only sets the state of the flags.

Return Values

If the representation was successfully stored, fegetexceptflag() returns 0. Otherwise, it returns
a non-zero value.

If the excepts argument is 0 or if all the specified exceptions
were successfully set, fesetexceptflag() returns 0. Otherwise, it returns a non-zero value.
